IMPROVEMENT IN POCKET PICTURE-EXHIBITORS.

Specification forming part of Letters Patent No. 178,206, dated May 30, 1876; application filed May 19, 1876.

To all whom it may concern: 7

Be it known that 1, CHARLES H. THOMPSON, of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pocket Picture Exhibitors; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to means for displaying pictures; and the object of the invention is to provide a panoramicpicture-exhibitor in 'a portable and condensed form, and which I design naming The Pocket Centennial Picture-Exhibitor, and it consists, essentially, of a metal case suitably ornamented, and constructed as hereinafter described.

as as, Fig. 1, in which A is the case, at the but ton for rotating the roll, and c the roll.

Fig. 3 is a vertical section through the line 3 3 Fig. 1, and shows the case A, the rolls 0, a tape, g, and bead 7) around the openings a.

Fig. 4 is an end view, showing the means of securing the rolls 0 in case A, and in which Bis the back cover of the case A. h is a tongue provided with a circular notch in its free end, and which is attached to and a part of the back B. The dotted lines m show a U-shaped notch cut into the ends of the box or case A, into which the rolls 0 are secured by the tongueh, when the case is completed, the back B being secured by asuitable fastening, so as to be easily removed.

The operation and manner of using my a a are oval openings in its front invention, is as follows: The picture to be used-as, for instance, the President of the United States, or the rulers of the nations of the earth-having been prepared on a tape or ribbon, and attached at its ends to in its place, at the same time serving as a bearing for it. Now, by rotating one of the rolls by means of the button d, the tape is of course unwound from the opposite roll and wound up on the one rotated. By this means the pictures on the tape are brought successively behind the openings at a, while there is any tape to unwind from the other roll. When all the pictures have been thus brought into view, the opposite roll is rotate-d in the opposite direction, which repeats the operation or reproduces the pictures. By the adjustable manner in which the rolls are secured, and the facility with which they may be removed, it is only required to provide additional tapes with various pictures on them to have a variety of panoramas while only using one case.

Having thus described my invention, What I desire to secure by Letters Patent is-- l. The case A, provided with slots m, and the removable back cover B with its tongues 12., securing a bearing for the roll 0, the whole forming a pocket picture-exhibitor, constructed and arranged substantially as described and shown.

2. The combination of case A, with its openings a a, U'shaped slot m, removable back cover B, tongues 11., and rolls 0 a, when arranged substantially as described, and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
